ZEPHYEUS. 393 
received specimens from Chang-yang, Central China. Probably this species 
occurs in Corea, but so far has not been recorded from that locality. 
Dr. Staudinger (Rom. sur Lep. iii. p. 139) states that Dorries found the 
larva of Z. attilia on oak, and described it as green with yellow dorsal 
streaks.

" Allied to T. attilia ; colour the same ; margin of primaries straighter. Above, the submarginal 
row of white spots in the secondaries larger and more distinct, the third, fourth, and the one 
near the anal angle centred with black ; below, the ground-colour slightly duskier, becoming 
still more so towards the margin ; in the primaries is a transverse bar in the middle of the 
cell, extending from the subcostal to the submedian vein, and almost divided by the median 
into two spots ; the discal bar ceases abruptly at the third median veinlet ; an extra small 
spot, just on the division between the middle and apical thirds, between the third median 
veinlet and the submedian vein : secondaries with a transverse row of three black spots at 
the base in a descending series from the costal vein, a short bar at the end of the cell as in 
primaries ; a transverse irregular bar in the middle third, extending from the costal and 
narrowing towards the independent vein ; a row of three oblong spots, the first two with 
the longer axis placed transversely, the third near the inner edge, almost at right angles to 
the second; a submarginal row of whitish spots centred with black, more distinct and 
enclosed in the aforesaid dusky colour ; the orange-red at the base of the tail and at the 
anal angle more suffused. Expanse of wings 1 inch 34 lines. 
" One specimen taken about the middle of August on the top of the peak, 1 060 feet high, over- 
looking Hakodate." (Fenton, I. c.) 
This appears to be a rare insect in Japan ; there was but one specimen in 
the collection of the late Mr. Hemy Pryer; this is from Yesso and is 
probably the example referred to by him in his book. Dr. Staudinger 
describes the species under the name of T. oberthiiri, and states that it was 
found on the Ussuri by Dorries, who also obtained it at Askold and Suifun in 
small numbers.
